Abstract: Stem and root rot is an important disease of sesame. To manage it in natural way, different oils of plant origin and several locally available oil cakes as well as manures were tested at different concentrations in vitro using poison food technique. Among different oils, Clove oil registered 100% mycelial inhibition at all concentrations followed by neem oil recording 72.57%, 81.86% and 80.66% and mustard oil registering 71.82%, 77.76% and 88.60% at 2%, 3% and 5% concentrations respectively. Among all organic products tested, extract of neem cake registered maximum growth inhition of 60%, 76.57% and 93.73% followed by Mustard cake (58.20%, 68.89%, 93.73%) and Mahua cake (51.53%,68.49%, 87.13%) at 3%, 4% and 5% concentrations respectively.
